Thanks Dmitry and peter

Is Logic OR, Logic AND and Logic XOR gates switching time are differ or same? assume all logic ICs are fabricated same technology   

I need to calculate time complexity and critical path delay of a multiplier architecture manually, which consists of a AND, OR and XOR logic gates. Is i can assign as a unit delay for all logic gates(AND, OR and XOR) or varying time delay between AND, OR and XOR?

good, i will go through spec sheets for reference

welcome Dmitry gorodetsky

which type of design want to do collaborate manner
